Re: Org mode fontification error in #<buffer myfile.org> in python and ipython source blocks

[Sebastian Gimeno]

Hi Jack,

I have cloned the git master. Running without configuration ("make vanilla"), emacs correctly fontifies the source block and it also gets exported to HTML. It seems that it is a configuration problem. Sorry for not double checking first!

Many thanks for your help!

Cheers,

Sebastian

Hi Jack,

thanks for replying!

The error does not happen using "emacs -q" (built-in package: org 9.3). I haven't tried with the git version yet. i will and let you know.

Cheers,

Sebastian

I'm unable to reproduce this behavior on emacs 27.1 and git
master. Fontification and export work fine with this code block for me.

Does the error still happen when you use emacs -q ? Or if you use git
master?
